How easy is it for you to get jumpseats or ride on pass travel? I guess what I'm asking is do you purchase tickets for travel when you must be some place?

My husband had jumpseat access on US-based carriers until 9/11. We still purchased a good portion of his tickets though because it was just too unreliable and often times we had too mush invested in the other end to risk him showing up a day or two late. If that's the case for you and you do find yourself buying tickets once in a while then it seems like it could be wise to collect miles. If you're only points earning would be through credit card purchases you might want to consider something that offers hotel rewards.
